Without the regen running I get close to what my 5.9 got. I think it's important to compare the same driver as we all drive different. When my wife drove my 5.9 she got about 13 to 15 and I would get 18 to 22. Same truck, different drivers. Your friend may be driving like me and you could be driving like my wife. 
I have not had any issues with my 6.7 and I just love it. I love the 6 speed auto and the exhaust break. |
yeah I know what you mean about different drivers, and I've tried it. My best milage was 16.5 and it was babied on the highway. Doesn't seem to matter how you drive it.
My AU flash did drop my milage a bit though. I used to get closer to 17.5 (overheard) and now it's closer to 15.8 (overhead). Hand calc dropped a bit too.
